Answer:
6z-7>8z+2? = z < -9/2
Step-by-step explanation:
6*z-7-(8*z+2)>0
-2z - 9 = -1 • (2z + 9
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
2z+9 < 0
Divide both sides by 2
z+(9/2) < 0
Subtract 9/2 from both sides
z < -9/2
Answer: z < -9/2

Answer: It will take the Dolphin 2 hours to swim 40 miles. The penguin will take 8 hours. The swordfish will take 2/3 of an hour, that is 40 minutes, to travel 40 miles.
Step-by-step explanation: Divide the given distance by the unit rate given:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour
This is the reverse of the process described in the question.
If the dolphin takes 2 hours to swim 40 miles, what is its unit rate? x ÷ y = R 40 miles÷2 hours= 20 mph.
40 miles ÷ 2/3 hour
3/2 × 40 = 60 mph
I hope this helps.
Answer:
Option B
can be used to find the area of the face of the lamp shade in square inches
Step-by-step explanation:
We know that the area of the Trapezoid is
Area ![A = \frac{a + b}{2} h](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D%20h)
where
a and b are the parallel sides
h is the height
Substituting the values from the figure
![A = \frac{6 + 10}{2} x](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B6%20%2B%2010%7D%7B2%7D%20x)
![A = \frac{1}{2}(6 +10) x](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%286%20%2B10%29%20x)
